Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and more specifically, to a tea drying and stir-frying device. Background Technology
[0002] Tea is a widely consumed beverage that originated in China and has a history of thousands of years. The drying and stir-frying process in tea processing is one of the key steps that determines the quality of tea. After the tea leaves are kneaded, they are evenly spread in a stir-frying machine and heated to further evaporate the moisture in the tea leaves. During the drying process, the tea leaves need to be constantly stirred to ensure that the tea leaves are heated evenly and to prevent local overheating or dampness.
[0003] During the process of tea leaves coming into contact with the inner cylinder, the tea leaves are brittle during drying. When they come into direct contact with the hard metal inner wall, the tea leaves will break, affecting the later sales. At the same time, the existing tea drying and frying devices have a single heating method, which can easily lead to uneven heating of the tea leaves. Some parts may be overheated, while others may be underheated, affecting the color, aroma and taste of the tea leaves. It may even cause the tea leaves to burn or not be completely dried.

The stir-frying bucket 3 is provided with a rotating shaft 10. A stir-frying rod 11 and a stir-frying plate 12 are axially arranged on the rotating shaft 10. The stir-frying rod 11 and the stir-frying plate 12 are hollow inside. An electric heating wire 13 is provided inside the stir-frying rod 11 and the stir-frying plate 12.

[0031] In this embodiment, tea leaves to be dried and stir-fried are added to the stir-frying barrel 3 through the feeding box 23. With the cooperation of the drive gear 15, the drive motor 14 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the stir-frying plate 12 and the stir-frying rod 11 to rotate. The heating plate 4 heats the stir-frying barrel 3 and stirs the tea leaves.

With the metal wire cylinder 8 with a rattan mesh cylinder 9 in the inner liner 7, the tea leaves are flexibly protected during the frequent stir-frying process, reducing the chance of tea breakage. When feeding, the latch 25 and the feeding plate are opened, and the drive cylinder 26 is started. The output end of the drive cylinder 26 drives the stir-frying barrel 3 to rotate at a certain angle, which facilitates the feeding of tea leaves.
[0032] Please see Figures 3-5 As one embodiment of the conductive device: a drive motor 14 is provided on one side of the rotating shaft 10.

[0033] More specifically, when the drive motor 14 drives the rotating shaft 10 to rotate, it is electrically connected to the first conductive ring 18 and the second conductive ring 19 through the external power supply line 22. The positions of the first conductive ring 18 and the second conductive ring 19 are fixed by the fixing bracket 17 and the fixing ring 16.

By setting a metal cylinder 5 with a heat preservation cylinder 6 in the stir-frying barrel 3, heat can be kept warm during the heat transfer process. In conjunction with the metal wire cylinder 8 with a rattan mesh cylinder 9 in the inner liner 7, the tea leaves are flexibly protected during the frequent stir-frying process, reducing the chance of tea breakage. When feeding, the lock 25 and the feeding plate are opened, and the drive cylinder 26 is started. The output end of the drive cylinder 26 drives the stir-frying barrel 3 to rotate at a certain angle, which facilitates the feeding of tea leaves.
[0035] When the drive motor 14 drives the rotating shaft 10 to rotate, it is electrically connected to the first conductive ring 18 and the second conductive ring 19 through the external power line 22. The positions of the first conductive ring 18 and the second conductive ring 19 are fixed by the fixing bracket 17 and the fixing ring 16. The electric heating wire 13 in the rotating shaft 10 and the stir-frying rod 11 contacts the first conductive ring 18 through the first conductive head 20, and the second conductive ring 19 contacts the second conductive head 21, thereby energizing the electric heating wire 13. After the electric heating wire 13 is energized and heated, it heats the stir-frying rod 11 and the stir-frying plate 12, further improving the drying and stir-frying efficiency and drying effect.
